Potentiometer circuitry, particularly as related to calibration, is discussed with the primary consideration given to the required circuit measurements.The more feasible means of calibrating potentiometers are described in considerable detail. Emphasis is Topic: Potentiometer--Calibration.
Universal Ratio Sets can be calibrated by a number of different methods. The well established methods are very briefly outlined and emphasis is placed on some more recent developments. The choice of methods will depend upon available laboratory equipment Topics: Measuring instruments., Calibration.

NBS estimates of uncertainties associated with physical measurements, and with some NBS calibration services, are shown by 66 provisional 'accuracy charts.'Each chart is accompanied by a facing page giving a brief statement of the state of the art and ten Topics: Physical measurements., Calibration.
The high-voltage calibration facility, in operation for seven years at the National Bureau of Standards Radio Standards Laboratory (RSL) but now at NBS Washington, is described with emphasis on several novel construction features and calibration technique Topics: Calibration., Electric measurements.
A simple technique is described for extrapolating the 1 kc values of certain two-terminal capacitors to higher frequencies without incurring serious losses in accuracy.The method is intended for use with air capacitors having binding post or banana plug t Topics: Shortwave radio., Radio measurements., Calibration.
The National Bureau of Standards has been calibrating many types of field strength meters and their related antennas at frequencies up to 1000 MHz for several years.Various techniques of measurement have been * investigated regarding accuracy, calibration Topics: Electronic apparatus and appliances., Calibration.
